Flower Fruits & Seed
Abeka Biology Chp 3
| Question | Answer |
|---|---|
| Sepals | The leaf like structures attached to the edge of the receptacle. |
| petals | The most conspicuous part of the flower. |
| corolla | Name when the petals are collected together. Some petals can be fused together to form 1 trumpet like structure. |
| stamen | Organs within the corolla that produce pollen. |
| filament | A slender, elongated stalk. |
| anther | Is the enlarged structure at the tip of the filament that produces pollen. |
| pollen | Tiny grains that consist of male reproductive cells with its own definite shape and size. |
| What is the purpose for Sepals? | To enclose & protect the flower's petals. |
| How do petals play an important role in pollination? | They attract insects with their showy colors & sweet nectar. |
| Name 2 parts of Stamen. | Filament & anther. |
| Pollen contains what reproductive cells? | Male reproductive cells called sperm. |
| Pistil | The elongated, vase shaped structure of a flower. |
| Name the 3 parts of the Pistil. | Stigma, style, and ovary. |
| Ovary | Swollen section located at the base of pistil. Holds the Ovules. |
| Ovules | Future seeds which contain the female reproductive cells known as egg cells. When fertilized, they develop into seeds. |
| Stigma | Top of pistil that is sticky and receives the pollen grains at pollination. |
| style | The stalklike structure that connects the ovary to the tip of the pistil. |
| bracts | Special leaves that appear to be its petals. |
| inflorescences | Plants that bear their flowers in clusters. |
| photoperiodism | Phenomenon where plants require a definite period of light and dark before they will produce flowers. |
| fruit | When ovary is fully ripened. |
| pollination | A process when pollen reaches the pistil to fuse with the ovules in the ovary. |
| hybrid | Cross-pollination between plants belonging to different species of the same plant. |
| nectar | A sweet tasting, watery liquid produced by plants. |
| fertilization | When ovules begin developing into seeds due to the sperm cell fusing with the egg cell. |
| sexual reproduction | The type of reproduction which sperm & egg unite. |
| legume | Simple fruit that consist of a pod enclosing several seeds. |
| bran | In wheat, a shell-like fruit covering. |
| chaff | Outer most layer of wheat. Covers the bran. |
| germination | Sprouting of a seed. |
| dormancy | When a plant stops growing for a period of time.. |
| ednosperm | Makes up 85% of wheat kernel and is the part used in making white flour. |
| Primary purpose of flowers to a plant? | To produce seeds for reproduction. |
| Another name for a flower stalk? | Pedicel |
| Chief factor affecting when most plants flower. | The length of daylight and night. |
| Eight groups of simple fruits. | Berries, drupes, pomes, legumes, samaras, nuts, grains, achenes |
| Five important cereal grains | Barley, oats, rye, corn, rice |
| Four parts of a wheat kernel | Husk, bran, endosperm, germ |
| Three main parts of a seed | embryo plant, endosperm, & seed coat |
| Three parts of embryo | Plumule, radicle, cotyledon(s) |
| Five factors that favor seed germination | the amount of moisture available, amount of oxygen available, temperature, soil conditions, amount of sunlight available. |
